For more than 50 years, Carlson Labs has been recognized as an innovator and leading educator in the field of high-quality nutritional supplements. As one of the first supplement companies to discover the value of all-natural vitamin E, they opened their doors in 1965 to offer the most complete line of natural-source vitamin E in the world. In 1982, they began educating retailers and consumers about the health benefits of omega-3 fatty acids and were one of the first companies to introduce cod liver oil and fish oil to the U.S. market. Today, we are proud to offer Vitamin D3, Nutra Support Diabetes, 5 HTP, Key E, Chelated Calcium-Magnesium, Ribose and other Carlson supplements designed with your family's unique nutritional needs in mind.
